Hi Igor,
The image of your cost distance raster makes it look like the cost distance to both points A and M is 0. If this is the case, when you run the cost path tool, it is generating 2 cost paths that are 0 cells long. One goes from point A to point A and the other goes from point M to point M.
If A is the point that you are trying to determine the cost distance and cost path from, then create a layer (or raster) with just point A and use that as the source when you run the cost distance tool.
This should result in a raster where the cost distance is 0 at point A and is some value greater than 0 at point M.
Then, for the cost path tool, you will want to use a layer (or raster) with just point M to represent the destination. This way the cost path will represent the path from point A (cost distance = 0) to a destination at point M.
